I currently race speedway with a VS IRS Commodore and have Low King springs in the rear of it, due to having little to no weight in the rear of the car the whole car is stripped out and only a 30L aluminium fuel tank in the boot, lows are pretty much standard height.
So I'm looking at getting some Superlows for the rear, but I am looking for which brand of Superlows has the softest spring rate from Kings, Lovells, Dobinson, Pedders and any other brands?
I'd shoot each company an email mate, i'll be doing that soon too.

if you're looking for soft springs in the back, is it altogether stupid to heat and compress the current springs?
It will be lower, and softer. So the wheels dont spin up everytime
You running on a flat or banked track? I have king KHRL 20's in my live axle VN with a 205/70r15 on the right rear and 205/65r15 on the left rear (thats all the width we're allowed) and i have had them bottoming out on a really tacky night.

Sweefu, I will sent off some emails today and try and get some Rates from the suppliers
Soop, The division I race in we have to race Anti-Clockwise and Clockwise arouns the track so I need to get both sides as even as possible
VN Racer, the tracks I race on are dirt tracks banked 6-8 degress, We run 215/65 on both rear tyres as we have to race in both directions, I have the Lows designed for the VS IRS and the car is basically at stock height in the rear and has a tonne of ground clearance so no chance of bottoming out at the moment
Only problem i see with going with any superlow spring is the fact that they'r designed for street applications mean they're probably going to be too hard and end up with you bouncing all over the place.
See what K-mac can do for you, I used them when I had some custom springs made to suit my subaru, you can dictate what spring rate you would like.
